OS: 3.0 BSDI BSD/OS 3.0 Kernel #0: Hardware: Pentium Pro 200 / DigiBoard / Cisco 2500 series / 8 33.6k externals. Problem: I can dial in with Win95 and get a solid tcp connection. Light transfers like WWW browsing appears to work fine but heavy transfers cause a hang which may correct in a minute or so, or may not. Typically, I will connect at 33.6 via Win 95 dialup networking and open a telnet session to the same server. Then I begin a winsock ftp transfer or Usenet retrieval. After a few minutes of 33kbps transfer, the transfer hangs and no more data appears to be moving through the modem. If I drop to dos and do a ping to the server, I get a time-out. Any other winsock apps will fail to run. Netstat will show the column headers then freeze. The telnet sessions is frozen. Sometimes, everything will begin moving again in a minute or so. On most occasions, though, it has remained frozen until I disconnect and re-connect. The modems remain connected with no problem, even for 8 hours or more. I have managed on occasion to download for up to 12 hours with no problem. At other times, I cannot move data for 15 minutes. This occurs with everyone using Win95 (we all do). Doesn't matter if its the original, OSR2 or the latest beta. Fiddling with modem settings makes no difference. Adding low MTU and RWin setting to the registry might improve things but not much. It doesn't matter if we're on the 'net or just ftping to/from the server. It doesn't matter to which of the eight modems we connect. It doesn't matter how many people are on-line. Any comments or suggestions regarding this problem would be greatly appreciated. Please cc: to my mailbox, as I don't know if my subscription request has been processed yet. TIA -- Dennis R.
